IPC: H01L23/50
Filed: 1986-09-26
Abstract: PURPOSE:To prevent the occurrence of a crack in a resin seal type package by forming a notch section to a tab as the mounting section of a pellet resin- sealed to the package so as to be notched in the radial direction. CONSTITUTION:A tab 8 is formed to an approximately square plate shape, and notches 10 are arranged to each of four sides at approximately regular pitches at every plural stripe to the outer periphery of the tab 8, and shaped extending over the whole so as to be notched in the radial direction in fixed width and fixed depth reaching no pellet. The notch sections 10 are formed at the same time as the stamping of the tab 8 by an edge for a press die punching the tab 8. Even when peeling is generated on the interface of the lower surface of the tab and a package or the tab and the pellet by repeated stress by thermal stress, stress is inhibited at a small value because the notch sections 10 are shaped at the outer periphery of the tab 8, thus preventing the working of excess Stress to the peeling section, then obviating a phenomenon in which cracks occur from the peeling section.

Title: Heating medium circulation type sealing roll
Inventor: HASHIMOTO RITSUO
IPC: C23C14/56
Filed: 1986-09-26
Abstract: PURPOSE:To prevent the sealing effect of a sealing roll from being reduced with thermal deformation thereof by allowing a heating medium to flow in the vicinity of the surface of the sealing roll in a vacuum deposition line. CONSTITUTION:A vapor deposited Zn layer is formed by introducing a steel sheet 301 into a vacuum vessel 303 in a vacuum deposition line and vacuum- depositing metal such as Zn on the surface of the steel sheet 301 in a vapor deposition chamber 305. In this case, the steel sheet 301 existing in the outside air is passed through plural sets of sealing rolls 302 and infiltrated into the vacuum vessel 303, and after vacuum deposition, it is again taken out to the atmosphere through the plural sets of sealing rolls. Since the sealing rolls are raised in temp. by the contact with the steel sheet 301 and temp. distribution is caused in the circumferential directions of the sealing rolls, the parts high in temp. are made to projecting forms, clearances are formed between these and the steel sheet, and sealing failure is generated. In this case, the sealing roll is formed by setting a sleeve 201 on a core part 202 having grooves 203 as a passage for a heating medium such as water and oil and thereby deforma tion is not caused because the sealing roll is cooled with the heating medium and therefore sealing capacity for air is prevented from being reduced.

Title: Printed circuit board fixing structure
Inventor: SUZUKI YOSHIJI
IPC: H05K7/14
Filed: 1989-09-01
Abstract: PURPOSE:To achieve a low-cost and reliable fixing of a printed circuit board by providing an elastic member which is bent by enabling a column-shaped gap to be contracted by pressure of a protruding line and a member to be mounted with a penetration hole where the elastic member can be unloaded, and a contraction-preventing member which can be freely inserted into or removed from the column-shaped gap and prevents contraction. CONSTITUTION:When a penetration hole 4a is positioned above a hook box 1 and a printed circuit board 4 is pressed, the lower part of the penetration hole 4a is allowed to contact the outer-periphery wall of engaging tongue pieces 1a and 1b and the inner- periphery surface of the penetration hole 4a descends while pressing protruding line parts 1f and 1g toward the inside. Then, when the printed circuit board 4 reaches a specified position, pressure for the engaging tongue pieces 1a and 1b is canceled and these engaging tongue pieces 1a and 1b return to the original form due to elasticity. Therefore, since the diameter of the outer-periphery wall of the protruding line parts 1f and 1g becomes larger than the penetration hole 4a, the printed circuit board 4 is clamped to the engaging tongue pieces 1a and 1b. Then, when a cap 2 is inserted into an air gap 1c, fixing operation is completed, thus enabling the printed circuit board 4 to be fixed at one tough and reducing assembly operation time.
